The Android 12 upgrade for US Galaxy S21 phones introduces a refresh rate bug that Samsung is trying to fix

Tech Highlights:

  • There is no amount of testing in limited batches that can predict what will happen when the One UI 4.0 interface versions is released to phones en masse, and the latest issue with the Galaxy S21 series display refresh rate lag is just another example. Many American owners of the phones in the S21 line started complaining that the official One UI 4.0 update broke their screens’ refresh rate. As soon as they lifted their fingers off the display, the refresh rate defaults back to 60Hz, making interface animations and other dynamic elements appear laggy and stuttering.

  • This year, Samsung did a fantastic job with the Android 12 upgrade on its Galaxy phones, with even Verizon and T-Mobile carrier models receiving the latest version months ahead of schedule. The speed is certainly due to Samsung’s several One UI 4.0 beta testing versions released prior to the Android 12 upgrade release to iron out any issues that may have arisen during the process.

Samsung has acknowledged the issue and a moderator in the Members community has escalated it for solving in a future update. The refresh rate problem seems to only affect phones equipped with Qualcomm’s latest Snapdragon 888 chipset, as Exynos models outside the US don’t seem to be affected.
